TO ALL WHOM IT MAY CONCERN:

Be it known that we, ANTON KEIL and JOHN TRESCH, of the city, county, and State of New York, have invented a new and improved Machine for Moulding Pottery; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part oi' this specification.

rhe object of this invention is to arrange a machine whereby flower-pots and similar articles of rottery can be moulded in the shortest possible time and in a simple manner. The invention consists in securing a iiask to an up-and-down sliding frame, and bringing it in contact with a revolving core. The ask is composed of a series of sections, which can be opened to remove the pot after the same is moulded. The bottom of the flask is also movable and can be pressed up to facilitate the removal of the ready moulded pot. The whole machine is arranged on one corner of a square or oblong frame, and on each corner of the frame may be arranged such an apparatus. All the shafts and appendages receive the motion from one horizontal drivingshaft, so that by one belt a machine may be driven by which four o1' more pots may be moulded at a time. In the annexed drawing our invention is illustrated- Figure 1 representing a side elevation of our improved machine; and

Figure@ a slide elevation partly in section, showing the iiasli elevated and the core inside of the same;

Figure 3 is a plan or top view of our invention.

Figure 4 is a horizontal sectional view of the same taken on a plane indicated by the line x x, iig. 2.

Similar letters of reference indicate likeparts.

A is lthe frame, which is made of metal or any other suitable material. It consists more particularly ot` four uprights, a, which are connected and strengthened by' braces and arms, as shown in the drawings. The horizontal drivingeshat't B is arranged on top of the frame A, and is hung ini boxes which are held in arms, c, projecting from the frame. The belt d transfers the motion from the shaft B to a hhaft, C, which is hung in suitable boxes near the lower end of the frame. At the end' oi' the shaft'C is arranged a crank, c, which is provided at its end with a pin,f, by means of which it raises a sliding plate, g, which is arranged on one side of the machine. When the shaft C is revolved in the direction of the arrow shown in g. 1, the pinf comes in contact with the lower edge of a projecting dan e, t, which is secured on the plate g, and thus raises the said plate until it is in the position shown in iig. 2. hen the pin is released from the lower edge of the flange, and

vthe plate g would suddenly fall down but for the curved extension h', of the flange L, by which the said plate is gradually guided down. The plate g is guided on the uprights a by suitable arms or guide plates. Upon it is arranged the flask D, which consists of six (more or less) plates c2, which are hinged near the bottom, by means of pins t', to arms or braces z", the latter' being secured to the supporting tube E. This tube is secured by means of bolts or screws to one end of the plate g. Within it is arranged a spiral spring, O, (shown in tig. 2,) which has the tendency to press a pin, K, up, the top plate K of said pin, 'forming the bottom of the liask. catch, Z, (iig. 2,) holds.the said pin and bottom down. released and will ily up, thereby raising the pot that may be contained in the dusk. The plates-cl are surrounded by a revolving ring, F, which is supported by a ring, f', which is rigidly fixed to or part of they tube E. The inner edge of the ring F, is shown in ig. 4, made in the shape ot' a ratchet-wheel, so that a knob, d, on cach plate d may tit into an eccentric space left between the flask and inner edge ot' the ring, (see Eg. 4.) A spiral spring, m, which is arranged between each plate cl and the tube E, (see iig. 2,) has the tendency to press the plates d apart, so that when the ring F is revolved by means of a handle, m', in the direction of the arrow, shown in iig. 4, the plates will be spread as shown in fig. l. By moving the handle m in the opposite direction, the ilask will be closed, as shown in figs. 2 and 4. A spring-catch, mi', which isarrangcd on top of the ring l", engages one of the knobs t, as seen in lig. e', and thus keeps the plate el firmly locked, until, by means oi' the handle on the spring-catch and by the revolution oi' the spring, the Hush is again opened. Above'the flask D is suspended, on the vertical shaft G, thc core H. The shaft G receives its motion from the shaft B by means of bevel gearing it. The core is made of the shape required, and is provided with cutting edges, o, (see Eg. 4,) whereby the clay is not only formed into the requisite shape, but also prevented from adhering to the core, after the operation of moulding is completed, as the sharp edges do not otter enough surface to the clay to A spring- As soon as the catch Z is pressed up the pin K will beA adhere to. A small pin, O', may be arranged on the tip'of the core to provide the hole in the bottom of the lower' pot, said pin being so arranged on a spiral spring inside of theA core 'that it may be pressed in more or less, so as to avoid any shock or concussion in case the said pin should come-in contact with the bottom K of the flask. As it is necessary that the core should revolve rapidly, and that the upward movement of the flask shouldbe slow, it is found necessary to conveyl the motion from the pulley g,von the shaft C, to the shaft C. in such a manner that the said shaft should run considerably slower than the said pulley. For this pnrpose'the pulley g turns loose on the shaft C, and a small pinion which is attached to the pulley q meshes into a gear-wheel, r, on a shaft, I. Thus the shaft I is turned considerably slower than the pulley g. A pinion, S, on the latter shaft gears into a large cog-wheel, t, which is mounted on the shaft C, and thus a very slow motion is conveyed from the pulley g to the shaft C, around which it revolves.

The operation of the machine is as follows: The flask D is lowered, and the plates al are locked, the pin K is held down. The ask is then tilled with clay, and is then raised so that the core nnay shape the inside oi' the pot. The ilask is then lowered by the 'mechanism before described and may then be opened. The spring catch [is pressed so that the plate K may raise the pot, which can then be easily removed. The flask is then again closed, refilled, and the operation repeated. Another plate, g, can be easily attached to the opposite side of the frame A, and a'tlaslr can be supported on each end of each plate, so that four flasks might be arranged on one frame. The frame may be extended indefinitely, so that a still larger number of flasks may be arranged thereon. It is evident that a eoremust be suspended above each flask. Thus a machine of this kind ean'be so arranged that one set of flasks is up while the other set is down, so that it' twenty flasks are arranged, ten flower-pots are continually being moulded while the ten other ilasks are being filled.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The cam e, on the shaft C, for thepurpose of raising the plate g and ilask D, substantially in the manner herein shown and described.

2. The combination of the curved Bange L on the plate g, with the pinf on the crank e,`for 'the purpose of gradually Ilowering the plate g, and flask D, substantially in the manner herein shown and described.

3. The construction of the flask D, so that the plates d may bespread apart or closed at will, substantially as and for the purpose herein shown and described.

4. The plate K on the pin K, in combination with the spiral spring and the spring-catch Z, for the purpose of raising the ready moulded pot,substantially as herein shown and described.

5. The manner of opening and closing the flask D, by means of the ring F and catch m, substantially asand for the purpose herein shown and described.

6. The combination of the ltrarne A, so that one or more flasks and cores may be arranged thereon, substantially as and for the purposes herein shown and described.

ANTON KEIL,

JOHN Tensen.
